I did factory reset of my phone, (Droid X), and I changed primary email, and I am not able to download any application from market. I get a message like application will be downloaded, but its never download app .

And I am using this same email id, as test account in developer account.

Now I am unable to start my phone. When I pulled the battery, phone went to off and till then I am not able start my phone. Please help me.

@pankaj That's very strange, pulling the battery while it's sitting at the bootloader shouldn't have hurt anything. Try a few more battery pulls and holding various keys while you power on, and try with and without USB plugged in (make sure the phone is charged as well). If that doesn't work, from what I understand you need to use RSDlite to re-flash your ROM. Instructions are here, though I haven't tested them myself ... use your judgement. Good luck!
